Sure, so long as all existing consumers of -Classes are okay with
the name change.  Technically we haven't release VTK 6 yet anyway.
IMO -Headers would be better than -Files.

Yes, the other info like ABSTRACT, WRAP_EXCLUDE, and WRAP_SPECIAL
is currently set with similar marks.

Yes.  Also the -Classes isn't loaded by default.  One must invoke
vtk_module_classes_load to get the list.  The basic module files
need to be very lightweight because they are loaded in a lot of
places.  In an early prototype I had lots more information in them
and it make VTK take *minutes* to configure even after the first
run.
